1. Multiply the voltage and the current to calculate electrical power in watts. For example, in a circuit charged with 50 volts and carrying a current of 3.5 amperes: power = 50 volts

Voltage induced due to current depends on the resistance of the load. If 1 ampere flows through 1 ohm resistance, 1 volt will be induced.
